Utility Reverse Node output is wrong

mayanim8 — Mon, 10 Dec 2018 18:21:49 GMT

I may not be using the reverse node correctly.

I am trying to connect the output of the transform node to go through the reverse node to get the negative value. However, the results I am getting are not equal.

For example: connecting Rotate attributes of two cubes through the reverse node. If I have connected Rotate Attributes of cubeA into the Input of the Reverse node, and then the output from the Reverse Node into the Rotate Attributes of cubeB.

When I input a value of 10 into Rotate Attributes of CubeA the value of Rotate Attributes of CubeB is -9.

Why is the value not -10?

Is this a bug, or do I have to set some kind of attribute on the Reverse node?

thanks

Hi!

https://help.autodesk.com/view/MAYAUL/2018/ENU/?guid=GUID-EECA80A5-FD6F-4A41-87FF-05461A2BEB2D

The node reverses black to white or "0" to "1"

this leads to "-1" to "2", ....

Just add an offset.

Hello mspeer,

Thanks for the link.

Just curious where would I add the offset? Would that be another node?

Or would this be a case of never using the reverse node to perform this kind of action, and use the multiply divide node instead?

Still trying to figure out these utility nodes.

thanks

Hi!

This is a Color Utility node, so it's working as it should.

For an offset just add another Utility node.

Use any node or node network you want.
